My sister got married, Li Rujin's heart was empty for a while, there was relief, there was loss, there was ease of unloading the burden, and there were also worries about his sister's future life, Li Rujin came to the room where his sister lived, pushed open the door, but found that his mother and younger brother Li Ruhu were already in the room.

Mom's eyes were still red, and when she saw Li Rujin coming, she hugged Li Rujin and cried bitterly, and the former bear child Li Ruhu also rarely quieted down, surrounded by the side, and her eyes were also red.

Li Rujin comforted for a while, the mother stopped crying, slowly quieted down, the former bear child also grew up, took his mother's hand, curled up beside his mother, and comforted his mother with practical actions.

A family of three sat in his sister's room until it was dark before leaving, before leaving, his mother wanted to lock his sister's room, but was stopped by Li Rujin. There are many sons-in-law who live in their mother-in-law's house, although this world is a feudal society, the daughter who marries out spills the water.

But there are still young couples who live in his mother-in-law's house, Li Rujin is thinking about letting his sister and brother-in-law run errands back and forth, living next to each other, ten days and ten days, excluding the last two days, 1357 lives in her mother's house, 2468 in her husband's house, the last two days, you are casual.

The Prince's Mansion is not far from the Li Mansion, and the walk is only ten miles away, and after dinner in the evening, I came over for a walk, and then chatted, and when it was late, I called back, saying that I would spend the night here, and I would not go back, which was logical.

And it won't be long before there is a ready-made good opportunity, Li Rujin's two wives are about to give birth, and my sister is going to be upgraded to be an aunt, and I will definitely come back to live for a few days during that time, first pull my sister over, and then let my sister bring my brother-in-law over, and everything will fall into place.

As soon as Li Rujin told his mother his thoughts, his mother immediately smiled, and immediately began to think about how to allocate the room, Li Mansion has few people and many rooms, and it is easy to free up two rooms, so he quickly selected two adjacent two rooms as a temporary palace when the young couple came back.

Li Rujin redesigned the two adjacent rooms and turned them into a suite, except for the lack of a kitchen, everything else is available, a small couple, a newlywed Yan'er, there must be a little privacy.

Considering that the two wives are both pot-bellied, Li Rujin adopts the prefabricated mode, makes the things first, and then directly knocks on the wall and installs them directly, it is estimated that one day is enough, Li Rujin went back to the room, first put the two wives to sleep, and went to the study to write and draw.

The next day, Li Rujin handed over the drawings to the housekeeper, this kind of thing, Li Rujin doesn't need to worry about it, the housekeeper will naturally handle it properly. Then I went around the research institute, checked the research progress, and went to other departments, and the institute gave Li Rujin a lot of surprises, such as the research and development of communication systems, the individual soldier communication system designed for individual soldiers has been successfully developed, and has achieved miniaturization, modularization, and quality.

In addition to the waterproof performance, the other performance is quite reliable, and now it has been produced in small batches, and the final test is done, waiting for the feedback from the troops.

Li Rujin adjusted the direction of research and development, began to develop large-scale wireless communication equipment, and now the communication of the Dawen Empire is still based on wired communication, limited by terrain and local conditions, and has not yet formed a communication network covering the whole country in the real sense.

Like most of the remote areas in the southwest, northwest and north of the empire, the empire's communications are simply out of reach, and if an emergency occurs, it is difficult to transmit information, which not only delays the fighters, but also brings a lot of inconvenience to the local people's lives.

Therefore, Li Rujin planned to build a wireless communication network that could cover the whole empire, mainly for the military, and some of it was open to the people to solve the problem of civilian communication. Now this plan is still an idea in Li Rujin's mind. It will take time for the real implementation.

At the same time, Li Rujin is also thinking about another thing, he is going to split the institute, many R&D departments are put together, with the continuous development of R&D progress, contradictions inevitably arise.

For example, in the process of engine research and development, it is inevitable that there will be huge noise, which is unavoidable, and with the increase of future research and development projects, such as the research and development of marine engines, the noise generation will be greater and more frequent.

Other R&D departments need a quiet environment, so that contradictions inevitably arise, and this contradiction is irreconcilable. And with the development of various R&D projects of the institute, the staff of the institute is also increasing.

It not only brings a huge burden to the logistics support, but also brings a lot of hidden dangers to the security system, and thousands of people in the entire research institute, even if there is one ill-intentioned, it is a huge security risk.

Therefore, the split of the R&D department is imminent. Li Rujin has already reported to the military department and the cabinet, and now the two sides are discussing, after all, splitting the institute is a huge project, and it will not be so simple.

Li Rujin walked around the research institute, thought about some questions, and went home, tomorrow is the day when the new aunt returns to the door, the family must prepare well, and Li Rujin will also hand over some secretly prepared things to his sister.

Back at home, the family is busy, to be honest, Li Rujin can't intervene at all, if he is allowed to intervene, it will be a mess, he is not here to help, he is purely here to make trouble.

Li Rujin had no choice but to take his two pot-bellied daughters-in-law out in circles, and now his wife is almost nine months pregnant, and there is still a month to go before the due date, so during this time, Li Rujin has increased the amount of exercise for his wife.

Li Rujin took his wife out of the door, followed by a group of entourage, some people carried food boxes, which contained snacks so that pregnant women could eat them at any time, as well as several healthy women and a doctor to prevent accidents.

Pregnant women can't be sad and happy, Li Rujin didn't let his wife attend his sister's wedding, but tomorrow is the day when his sister returns to the door, and the two daughters also miss their sister very much, Li Rujin plans to let his wife accompany his sister tomorrow, and just let his wife and sister talk privately.

For the two wives, Li Rujin is really very satisfied, but also deeply guilty, since the marriage, Li Rujin has been running around most of the time, and his wife gets together less and leaves more, especially during the period of pregnancy, Li Rujin is busy with the construction of Baoshan Iron and Steel Plant, most of the time in Huhai, not able to accompany him.

During pregnancy, it is a time when a woman is most helpless and afraid of loneliness, the second daughter has no complaints, and supports Li Rujin with practical actions, and even rarely calls Li Rujin, only if she really misses it, she will call him, while calling, crying, that woman doesn't want her husband to be by her side!

Li Rujin carefully helped his wife to slip around the street in front of his house, and the spring sun sprinkled on their bodies through the still tender green leaves, with a trace of warmth and happiness. 8)
